Abstract
The invention discloses a loose-leaf type vertical shaft fluid generator set, which comprises a loose-leaf blade 1, a loose-leaf rotating shaft 2, a frame 3, a loose-leaf shaft ring 4 and a vertical rotating shaft 5, wherein the loose-leaf blade 1 can rotate around the loose-leaf rotating shaft; two large blades 6 and 7 rotate around the vertical rotating shaft 5; according to the whole vertical shaft fluid wind generating set, the positive windproof blade 6 and the reverse windproof blade 7 are formed under the action of wind power perpendicular to a vertical shaft; and when wind is positively blocked, the loose-leaf blade 1 draws close to the frame under the action of the wind power, and when the wind is reversely blocked, the loose-leaf blade 1 is separated from the frame. Therefore, a positive windproof area is enlarged, and a reverse windproof area is reduced, power through which the rotating shaft of the vertical shaft continuously rotates is obtained.
Description
Technical field
The present invention relates to fluid power-generation, this explanation is main with wind-power electricity generation mainly, and the present invention also is applicable to the flowing water generating certainly.
Background technique
Wind power generating set is from wind, to extract the device of energy, and wind power generating set is mainly divided vertical axis aerogenerator group and horizontal wind power generating set.The vertical axis aerogenerator group is because of general gain the name vertical with attachment face of its wind wheel surface of revolution.On behalf of type, it mainly contain Dari eritrea type, straight wing type and Sa Woniusi type etc.How to change no matter the major character of vertical axis aerogenerator group is a wind direction, its blowing area is constant, does not therefore need travel direction control.The vertical axis aerogenerator group need will not rotated according to wind direction as the horizontal axis wind-driven generator group Just because of this; Otherwise the fan blade rotating speed is slack-off or stop operating; Yet be engraved in variation during the direction of nature apoplexy; And horizontal wind power generating set can not be at any time the change direction, constantly corresponding with wind direction.But still a large amount of horizontal axis wind generatings that using in today wind power plant; Be because we are less in the technological accumulation of aerodynamics and tectonic dynamics direction, cause the too low novel practical type research and development of wind power utilization rate of existing vertical axis wind power generation to relatively lag behind.
The patent of invention content
The problem that the patent of invention technology solves is: overcome existing vertical axis wind power generation technical deficiency, how to increase forward shelves wind area and reduce reverse shelves wind area, improve wind power conversion efficiency thereby increase the vertical shaft moment of rotation.
What patent of invention solved is: utilize wind; That under positive wind, blows loose-leaf with the superimposed pass just as door of framework; Shelves wind area is a whole blade; Reverse side becomes the windward side loose-leaf and is blown open just as door is opened with framework after whole blade rotation half cycle, has so just reduced a grade wind area, and a grade wind area is a framework.
The patent of invention application principle

Embodiment
Below with embodiments of the present invention are described with reference to the accompanying drawings.
Embodiment one: as shown in Figure 5, loose-leaf page or leaf sheet 1 links together through the loose-leaf axle collar 4 and framework 3, and loose-leaf page or leaf sheet 1 can be in the cofree rotation of framework but the angle limits of rotating is that loose-leaf page or leaf sheet is vertical with framework being an angle of 90 degrees to the maximum.
During work, when the wind forward blew to blade, loose-leaf page or leaf sheet 1 can make it closed with the door of framework 3 formation to the framework swing under the effect of wind-force, and at this moment the choke area of framework 3 is whole area projection A on the wind direction vertical surface of framework
Just(the area sum of skeleton and loose-leaf page or leaf sheet)
When the page or leaf sheet forwarded reverse position to, like Fig. 6, loose-leaf page or leaf sheet 1 was under the effect of wind-force, and pendulum is from framework, and at this moment loose-leaf page or leaf sheet 1 is opened with the door that framework forms, and the choke area of framework is the projection A of skeleton on the wind direction vertical surface
Instead, so just dwindled reverse choke area.
Embodiment two: shown in Figure 7; This is the schematic representation of vertical shaft wind energy conversion equipment under wind that has two blades; The same with general vertical axis aerogenerator group, blade is responsible for from wind, obtaining energy, and support mainly is responsible for the rotating force that blade produces is passed to rotating shaft.Blade obtains energy in wind mode is: be the correct time of wind as a blade 6, another blade one is decided to be reverse (like the blade 7) of wind.Thereby always have forward loose-leaf page or leaf sheet 1 near framework 3 form the door of closing keep a forward choke area be the whole blade area in the projection of vertically-supplying air to face, reverse loose-leaf page or leaf sheet 1 pendulum from framework 3 form the door of opening one by one (like blade 7) thus making reverse choke area is that framework is in the projection of vertically-supplying air to face.Become backward vane 7 behind the forward blade 6 rotation half cycles; 7 of backward vanes become forward blade 6.Continuous like this replacing guarantees F
AlwaysThereby always greater than the zero rotation that vertical rotation axis 4 is not stopped.All only can rotate as long as wind direction is vertical with vertical shaft or have vertical component, wind direction how to change vertical shaft towards a direction of design.
Belong to related domain professional and technical personnel's known technology as detailed description in the patent specification of the present invention.
Patent of the present invention is not limited to the protection content that claim and specific embodiment are addressed, so long as any invention of creating out according to design of the present invention all should belong within the scope of patent protection of the present invention.
